I have a biter too!

Within a week if the parents believe in spanking and within the month if they don't. As for at your house a redirect should be to a segregated place such as an exersaucer with as much activities removed or to a playpen where she can see all the fun but not participate. Then with time your no can be "no, stop or you are in the naughty spot" or whatever you wish to call it - know a friend who had a lady bug exersaucer and called it the naughty bug and that is where those needing time out went.

While I don't believe in teaching kids to fight back I do believe in teaching them to stand up for themselves/protect themselves. Teaching your son to put his arms out to keep the child at arm's length might make him feel more powerful.

Also don't be quite so swift to "rescue" your son in the sense that he has also learned a quick way to get your attention away from the group of kids and you don't want to feed into that. He needs to master not playing the victim before he is one. Instead of rescuing him, pick up the girl and move her to a different area saying XXXX doesn't want to play right now. Then move back from the group and back to observing. If she moves back, repeat with words and gesturing and only physically intervene if she doesn't listen to which she goes to the naughty spot - for disobedience of a command - you do as you are told at my house.

It is hard when it is our own child that is the target and part of the reason is that the other one year old sees your child as a threat to her getting whatever she wants be it a toy, your attention, etc.

This is also one of those things where being more physical than no is needed to teach. No means no but no to what - biting, walking across the carpet, bending over, what.... Putting your hand over the child's mouth - (yours is big enough she won't be able to bite you) then saying no we don't bite shows the child what you are talking about. Then the next time or two you go to her and say no - putting her hands over her mouth saying our mouths are not for biting other people or something like that. Often there is a bout of teething that happens during a biting phase too and if that is the case then it resolves when tooth has cut through.
